A ctl refusal quotes the offending word alone, everywhere: wrong #args in control message "Newcol", not "Newcol 2"

Some refusals quoted the whole line, arguments and all ("Newcol 2",
"Verbose maybe", "lock x"), others the word alone ("Theme", "Mount"),
so a script matching one could not match the other. Every ctl
refusal, the root's, a pane's and a column's, now quotes the message's
word alone, and one too long to quote whole gives up its middle.
